Coat and looks how to spot one

short, thick and dense

A tall, stately hound with long ears and a short, very dense coat. Fine black and white mottling blends into a slate-blue look, set off by black head patches and tan marks above the eyes.132

Coloursblack and white mottled (slate blue) with black patches and tan markings123

Personality what they are like

Quietly dignified and even-tempered, this hound is friendly with people and focused and determined on a trail. It is a natural pack dog with a rich, deep bay, and it can seem relaxed at home once its exercise needs are met.124

Daily activity how busy a day looks

High: plan on two hours or more of walking daily plus safe off-lead running and chances to use its nose, such as scent work or tracking.4

Grooming and care the hands-on bits

Easy care: brush every few days and check paws and long ears after outings.4

Home where they are happiest

Best in a spacious, rural or active home with secure outdoor space.42

Company who they like around

A pack hound by nature that enjoys canine company; early socialisation with other pets and livestock is recommended.14

The story where it all began

One of France's oldest scent hounds, it formed the hunting packs of Gaston Fébus, Count of Foix, in the 1300s and later of King Henry IV. It became the root stock of the southern French hounds and reached America in the 1700s.13

Fun facts for the dinner table

  1. 1

    In 1785 the Marquis de Lafayette sent seven of these hounds to George Washington, who likened their voices to the bells of Moscow.3

  2. 2

    In Britain the breed is sometimes nicknamed the 'Frenchie'.3

  3. 3

    It helped shape other hounds, including the Gascon Saintongeois, the Bluetick Coonhound and the Dumfriesshire Hound.3

  4. 4

    The tan spots above its eyes give the classic 'four-eyed' face described in the standard.1

Owner questions the things everyone asks

How often should I feed my Grand Bleu de Gascogne, and at what times?

Feed your adult Grand Bleu de Gascogne at least two meals a day, as their stomach empties within a few hours. Puppies need three to four smaller meals. For exact amounts, check the food label and ask your vet.5

What should a Grand Bleu de Gascogne eat, and which foods are dangerous?

Feed a high-quality dog food suitable for their age and activity level. Dangerous foods include chocolate, grapes, raisins, onions, garlic, xylitol, and macadamia nuts, which are especially harmful to dogs.6

How often should I bathe a Grand Bleu de Gascogne?

Furry Diary's starting plan suggests a bath every eight weeks, though the ASPCA recommends at least once every three months. Bathe more often if your dog gets very dirty or has skin issues.7 Furry Diary plan

How often does a Grand Bleu de Gascogne need brushing?

Brush your Grand Bleu de Gascogne every few days to keep its short, dense coat healthy. Furry Diary's plan suggests weekly brushing, which is perfect for this easy-care breed.4 Furry Diary plan

How do I trim a Grand Bleu de Gascogne's nails, and how often?

Trim nails every four weeks or sooner if you hear them clicking on the floor. Cut a little at a time, stopping before the quick to avoid bleeding.7 Furry Diary plan

How much exercise does a Grand Bleu de Gascogne need?

This active hound needs two hours or more of walking daily, plus safe off-lead running and scent work. Furry Diary's plan includes daily walks and play to keep them happy.4 Furry Diary plan

How do I look after a Grand Bleu de Gascogne's teeth and ears?

Brush teeth two to three times a week with dog toothpaste, never human toothpaste. Check floppy ears weekly for moisture and clean gently without pushing anything into the ear canal.7 Furry Diary plan

How long does a Grand Bleu de Gascogne live?

The Grand Bleu de Gascogne typically lives between 10 and 12 years. Senior years usually start around age 7, so regular vet checkups become even more important then.4 Furry Diary plan

Is a Grand Bleu de Gascogne good with children and other pets?

Yes, this breed is friendly and even-tempered, and as a natural pack dog it enjoys canine company. Early socialisation with children, other pets, and livestock is recommended.14

Can a Grand Bleu de Gascogne be left alone?

This pack-oriented hound prefers company and may struggle with long periods alone. It's best suited to a home where someone is around most of the time or where it has canine companionship.14
